Android

According to Google Play meta data policy:

I cannot add "Word blocks and vertical/horizontal word lists" in my store listing full description.

I have written instructions for my app in this manner. Am i violating their policy? I think I'm not because these are sentences not word lists. What do you think?

Here’s how it works:
Download the Example on-demand delivery app on your preferred device
Sign-up by providing your necessary details (name, phone, and e-mail address)
Set your pick-up and drop off locations
Choose a payment method (card or cash)
Enter your shipping details, the receiver’s name, and phone (if it’s not you)
Confirm the booking

Thanks in advance for the replies.

Hello my dear friends .  How can I get the geographic coordinates in which I am offline? Thank you for your reply.

hi !

I have a small win32 (18k) app that i developed years ago for my electronic hobby project. Basically, it takes the text from the screen or from a file, stores it internally in arrays and writes at regular time intervals data packets to the COM1 port(as a file). On windows and linux(using wine) on my PC i used a virtual COM port and installed a driver for a rs232 to usb adapter(ft232 chipset). I want the same on android. The win32 app was written in C, the only language i know, and i would like to port the app "as is"(no code rewriting) to android, because i have no clue of android programming at all. The search on the internet returned no results - i didn't find any solution. Is the following way possible :

General : Installing a minimal linux distro on android with usb acces/ Installing FT232 driver in the terminal

1.compiling the code for arm(32) linux/ Run it in the terminal
Or

2. Port the exe to windows rt/arm / Run the .exe with wine in the terminal ?

The linux distros in the android app(userland, andronix) are bare-bone ones and do not seem to provide usb support( when i run lsusb i get -99 code error) I've also installed visual studio 2019 (win 10 SDK) and cannot build my project because .h files are not found, even if i change the path in the project properties. If i enter the complete path in my code file they are found, but then i still have 200 error messages because things like Bool, Handle, are not defined. The original/initial application i build 10 years ago was generated by CodeBlocks on my old PC which i dont have anymore(broken,but i still have all original project files).
The project files can be found here (link temporary available for your analisys and answers): https://drive.google.com/file/d/1DTcnfRDubXJN12wzhC8KzvhW97AQn1uA/view?usp=drivesdk

Thanks.
